Could you please help me to delete an item from a multidimensional array? For example how can I delete the first range of in_matrix below? vector<CArrayInt*> int_matrix; for(int i=0;i<10;i++){ CArrayInt *int_vector = new CArrayInt(); for(int j=0;j<10;j++){ int_vector.Add(OrderTicket()); } int_matrix.Add(int_vector); } int_matrix.Delete(0); //// DOESN'T WORK Thanks a lot
